My flight was not delayed, but my family had a flight earlier in the week that was, by 5 hours. My daughter says she'll never book a late afternoon flight as they seem most likely to be delayed. I personally like the timing and usually they cost less. Also, get on the plan with fully charged devices or a non-electronic form on entertainment.

Allow time for TSA (I had) or figure out the priority boarding (I didn't but will look into it for future flights), I thought they were pretty inefficient. A guy behind me was freaking out because he was going to miss his flight and a bunch of us let him cut the line in hopes he could make it.

I was very impressed at how Alaska Airlines handles people with medical needs.

I upgraded my seat and the service and boarding were wonderful. My flight attendant was very helpful when I experienced nausea on the flight (a first time experience). Flight arrived early which was nice. The only negative was many airlines have screens to provide some on flight entertainment, this aircraft did not. I had planned to read and listen to an audiobook on my flights, so no big deal on my part. The USB plug ins were broken on both my seat and the center seat, so I was not able to charge my phone during the flight, I will add 2 of the three USBs were broken on ride from San Diego as well. I would attribute this to the design, it is a very awkward angle to plug in, so frequent and perhaps not so gentle attempts to plug in have caused them to break.

Delay of 4 hours, i understand there was a medical emergency, but the fact that they arrived without the medical equipment and didnt have a replacement on the airport was annoying because they told us supposedly their manager went for one replacement to JFK airport and cross the city on traffic i mean seems so unprofessional! Anyways at least the flight was safe!

Wish to have a little cushion for my lower back.

I had never flown Alaska Airlines before. I’ll definitely use them again. Seats were comfortable and roomier than expected.

My Favourite Airline, only wish it had more direct flight options from EWR to San Diego and Seattle.

This was my return flight. Everything met or exceeded my expectations. Crew was polite and friendly. Two small snacks and beverages were served during the 5 hour flight. Flight was not full so I had a bank of seats to myself. Being long legged, I might have liked a little more leg room, but it was okay. The flight to my destination had tons of leg room, I expect it was because I was in an exit row then. Loading went quickly and we arrived early. There was very little to complain about by today's standards.

That they have Water and non-alcoholic beverages! Love being hydrated on flights

I understand kids, as I have 2 of my own. When parents let toddlers jump on the tray tables, scream at the top of their lungs and disrupt everyone around them, the crew should get involved and put a stop to it. My 5+ hour flight back home to San Diego was horrendous because of this experience. I paid a good amount of money for my flight and shouldn't have to deal with that kind of chaos on my flight. Additionally, maybe masks should be required again since both passengers on each side of me were coughing and sneezing consistently without covering their mouths. I am sick now, because of it.

Our boarding gate was changed FOUR times; poor planning inconvenienced many seniors
